[jboss-user] [JBoss Seam] - Seam saying Datamodel saying row is Unavailable... WHY???

[tony.herstell@gmail.com]

Given:


  |     @DataModel("displayableCategoryDatamodel")
  |     private LinkedHashSet<DisplayableCategory> displayableCategorySet;
  | 
  |     @DataModelSelection("displayableCategoryDatamodel")
  |     private DisplayableCategory selectedDisplayableCategory;
  | 
  |     @DataModel("keywordsDatamodel")
  |     private LinkedHashSet<Keyword> keywordsSet;
  | 
  |     @DataModelSelection("keywordsDatamodel")
  |     private Keyword selectedKeyword;
  | 


The first time a member is added to keywordsSet and a page is displayed using the Datamodel then I get this:

The initial set is created using:

  |         // Create the default set of Keywords.
  |         keywordsSet = new LinkedHashSet<Keyword>();
  | 

a member is added using


  |     public void addKeyword() {
  |         Keyword newKeyword = new Keyword();
  |         newKeyword.setKeyword(getNewKeyword());
  |         keywordsSet.add(newKeyword);
  |     }
  | 

Keyword is:

  | @Entity // Defines this as an Entity that is a class mapped to the Datastore.
  | @Name("keyword") // Name used within SEAM for an instance of this class.
  | @Role(name="keywordSearchCriteria", scope=SESSION) // Another named instance of this class (used in the session scope).
  | public class Keyword implements Serializable {
  |     
  |     private Long id;
  |     private Integer version; // Hiberante Docs: EJB3 sais Timestamp actually but recommend Integer
  |     private String keyword;
  |     private Administration administration;
  | 
  |     public Keyword() {
  |     }
  | 
  |     @Id
  |     @GeneratedValue
  |     public Long getId() {
  |         return id;
  |     }
  | 
  |     public void setId(Long id) {
  |         this.id = id;
  |     }
  | 
  |     @Version
  |     @Column(name="version4OptLock")
  |     public Integer getVersion() {
  |         return version;
  |     }
  | 
  |     public void setVersion(Integer version) {
  |         this.version = version;
  |     }
  |     
  |     @NotNull(message="required")
  |     @Length(max = 30)
  |     public String getKeyword() {
  |         return keyword;
  |     }
  | 
  |     public void setKeyword(String keyword) {
  |         this.keyword = keyword;
  |     }
  |     
  |     @Embedded
  |     public Administration getAdministration() {
  |         return administration; 
  |     }
  | 
  |     public void setAdministration (Administration administration) {
  |         this.administration = administration; 
  |     }
  |     
  |     @Override
  |     public String toString() {
  |         return getKeywordAsText(this);
  |     }
  |     
  |     public static String getKeywordAsText(Keyword keyword) {
  |         StringBuffer infoToReturn = new StringBuffer("Keyword");
  |         infoToReturn.append(" (Id => " + keyword.getId());
  |         infoToReturn.append(", Version => " + keyword.getVersion());
  |         infoToReturn.append(", Keyword => " + keyword.getKeyword());
  |         if (keyword.getAdministration() != null) {
  |             infoToReturn.append(", Administration --> " + keyword.getAdministration());
  |         }
  |         infoToReturn.append(")");
  |         return infoToReturn.toString();
  |     }
